Description

Specification

Packaging cushioning technology

According to the present invention, for example, when electronic devices such as audio devices, televisions, and speaker devices, and other articles are stored in a packaging box and packaged, they are arranged between the packaged articles and the packaging box. The present invention relates to a cushioning material for packaging for cushioning an article by cushioning an externally applied impact force, and in particular, has a contact surface formed of pulp mold to support the packaged article over a wide area, and The present invention relates to a cushioning material for packaging capable of protecting a packaged article from an applied impact force. Background art

Conventionally, in general, for example, as a packaging material for electronic devices such as audio devices and televisions, and food products such as vegetables, fruits, and seafood, a Styrofoam ′ molded article formed of Styrofoam has been used. Since this styrofoam molded article is lightweight and has relatively high strength, it is used in large quantities as a cushioning material and a packaging container. As described above, the Styrofoam molded article is an excellent material as a cushioning material / packaging container, but on the other hand, it has various problems in disposal after use.

For example, when incinerating Styrofoam, the incinerator is damaged due to the high heat generated during combustion. Further, when styrofoam is directly embedded in soil for disposal, there is a problem that styrofoam is not decomposed in the soil and remains without being soild.

Due to such environmental problems and effective use of resources, in recent years, waste paper such as newspapers and magazines has been mainly used as a substitute for styrofoam. A cushioning material and a packaging container using a pulp mold as a filler have been developed. As a cushioning material for packaging using such a pulp mold, for example, a molding for packaging pad as disclosed in FIGS. 2 and 3 of Japanese Patent Application Laid-Open No. H11-1875851 is known. There is a body. FIGS. 2 and 3 of this publication are shown as FIGS. 15 and 16 of the present application.

As shown in FIGS. 15 and 16, the molded product 1 for a packaging pad is used to fix an object to be packaged, for example, a lighting device composed of a lighting device body 2 and a cinema 3 in a packaging box 4. It is made of pulp molding that is integrally molded with a mold. At a substantially central portion of the molding 1 for a packaging pad, a bent portion 5 having a V-shaped cross section is provided so that the bent portion 5 can be bent inward or outward. On the other hand, on the other hand, a curved portion corresponding to the side surface shape of the shade 3 or a contact portion 7 which is a contact rib is provided on one side.

Further, a protruding edge portion 10 having a grip portion 9 which is bent inward to grip the edge 8 of the lighting fixture body 2 at the tip is formed so as to protrude closer to the bent portion 5 than the contact portion 7. At the same time, on the other hand 11, a recess 13 supporting the support portion 12 of the lighting fixture main body 2 is provided at the edge thereof, and furthermore, the ridge 14 of the lighting fixture main body 2 is held. The holding groove 15 is formed. In addition, a locking portion 16 that locks the opposing surfaces when they are in close contact with each other is formed on the opposing surfaces of the bent portion 5.

. Reference numeral 17 denotes a reinforcing rib provided on the other side 11.

According to the molded product 1 for a packaging pad, after being arranged at the corner in the packaging box 4 and then placing the seed 3 thereon, the protruding edge portion 10 formed on the other hand 6 forms It is fixed while being pinched. Thereby, in the packaging box 4, the swing of the seed 3 can be prevented, the impact can be reduced, and the lighting fixture can be prevented from being damaged.

However, such a conventional cushioning material for packaging can sufficiently satisfy the performance required for this kind of cushioning material. There was a problem that it was not something. In other words, the cushioning material for packaging includes a vibration test to test how much the vibration as an external input is transmitted to the packaged article and transmits it. There is a drop test to test whether or not the test is transmitted. Each tester determines the quality of the test based on its own standard, and uses a test that satisfies each standard.

In this case, in the above-mentioned conventional cushioning material for packaging, while the side surface of the shield 3 is abutted, the abutment portion is provided on 6 and the other portion 11 on which the lighting fixture body 2 is mounted is provided on the other side 11. Had a structure with a reinforcing lip 17, so for example, in order to have a sufficient buffer function for drop tests, the rigidity of the contact part 7 and the reinforcing rib 17 were set large. It is necessary to be able to absorb the impact when falling.

However, when the rigidity of the contact portion 7 and the reinforcing rib 17 is increased, the shade 3 and the lighting fixture body 2 are supported by the linear projections formed by the contact portion 7 and the reinforcing rib 17, and both are supported. There will be line contact. Therefore, in the drop test, if the surface of the shade 3 or the luminaire main body 2 is painted, the paint is likely to be peeled off by the impact force of the abutment part 7 and the catching rib 17 There was a problem that.

In addition, in the case of the vibration test, if the rigidity of the contact portion 7 and the reinforcing rib 17 is large, the linear contact portion 7 and the reinforcing rib 17 will cause the seed 3 and the lighting fixture 2 There was a problem that the paint on the shade 3 and the lighting device body 2 was easily damaged due to the rubbing against the surface. In order to prevent the paint from being damaged, it is necessary to widen the receiving surfaces of the contact part 7 and the reinforcing rib 17 to receive the shade 3 and the lighting fixture body 2 in a larger area. However, a large receiving surface was not secured.

Therefore, using a conventional pulp mold cushioning material, a sufficiently large cushioning area is ensured while securing a large contact area with the lighting fixture body 2 and the shield 3. It was necessary to increase the thickness of the pulp mold and to increase the length of the cushioning part in order to provide impact capacity. As a result, there has been a problem that the weight and size of this type of cushioning material are increased, so that not only the amount of pulp monoredo used is increased, but also the entire packaging form is enlarged.

The present invention has been made in view of such a conventional problem, and is formed by using a relatively small amount of pulp mold. It is an object of the present invention to provide a cushioning material for packaging that can gently protect articles and prevent the coating articles from peeling off or scratching.
